A key open question in economics is the practical, portable modeling of bounded rationality. In this short note, I report on ongoing progress that is more fully developed elsewhere. I present some results from a new model with boundedly rational features in which the decision-maker (DM) builds a...

Empirical evidence shows that macroeconomic fundamentals have little explanatory power for nominal exchange rates. On the other hand, the recent ‘microstructure approach to exchange rates’ has shown that most exchange rate volatility at short to medium horizons is related to order flows....

We examine formally Keynes' idea that higher order beliefs can drive a wedge between an asset price and its fundamental value based on expected future payoffs. Higher order expectations add an additional term to a standard asset pricing equation. We call this the higher order wedge, which...

In a market with short term agents and heterogeneous information, when liquidity trading displays persistence, prices reflect average expectations about fundamentals and liquidity trading. Informed investors exploit a private learning channel to infer the demand of liquidity traders from the...

Previous research shows that firms shroud high add-on prices in competitive markets with naive consumers leading to inefficiency. We analyze the effects of regulatory intervention via educating naive consumers on equilibrium prices and welfare. Our model allows firms to shroud, unshroud, or...

This Paper presents a model in which boundedly rational members of an administrative staff calculate resource allocations in real time. We consider a class of hierarchical procedures in which information about payoff functions flows up and is aggregated by a hierarchy, while allocations flow...

I study how savers allocate funds between boundedly rational firms which follow simple pricing rules. Firms need cash to pay their inputs in advance, and savers-shareholders allocate cash between them so as to maximize their rate of return. When the rate of return on each firm is observed, there...

We examine how a firm's changing environment and the information constraints of its managers interact as determinants of the size of the firm's administration. Following the recent decentralised information processing literature, we assume that it takes individual managers time to process...

When a firm decides which products to offer or put on display, it takes into account the products' ability to attract attention to the brand name as a whole. Thus, the value of a product to the firm emanates from the consumer demand it directly meets, as well as the indirect demand it generates...

We study a market model in which competing firms use costly marketing devices to influence the set of alternatives which consumers perceive as relevant. Consumers in our model are boundedly rational in the sense that they have an imperfect perception of what is relevant to their decision...
